My concern with this sort of move is that some developers who would be prepared to deal with a DRM-free platform if that's all that was on offer, will instead choose to make apps DRM only if it seems like an easy choice. If that happens we'll get the split that Android has between the 'developer' and normal phones and there'll be an overall chilling effect on the Maemo ecosystem. Plus, people will inevitably try to break the DRM system which will put Nokia in direct opposition to a large chunk of their (potential) developers.

All this to support a model the music industry's already moving away from - it doesn't seem worth it.
